I just published open materials from our "AI Academy" for engineering faculty. Session 4 tackled the big shift: AI now does much more than answer your questions. It can go away, do research, and come back with a deliverable—faculty need the framework to understand this.

Good benchmarks allow a user to choose the best method for a particular application. “But the first question is, what do we mean by ‘better’?” Fascinating story by @drmichaelbrooks.bsky.social on benchmarking in #AI. Thx @labarba.bsky.social for the suggestion! 🧪 www.nature.com/articles/d41...

Is your AI benchmark lying to you?
Artificial intelligence models are too often assessed against flawed goals — a stumbling block for progress.

CHAP. CLVIII. — An Act to establish a Department of Education.

Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled, That there shall be established, at the city of Washington, a department of education, for the purpose of collecting such statistics and facts as shall show the condition and progress of education in the several States and Territories, and of diffusing such information respecting the organization and management of schools and school systems, and methods of teaching, as shall aid the people of the United States in the establishment and maintenance of efficient school systems, and otherwise promote the cause of education throughout the country.

We absolutely need to deliberately teach students how to use a variety of AI tools, and so-called "AI skills" are real and more difficult than they appear. The temptation to overuse AI to skirt the hard work of authentic learning is strong! Unsupported, students' use of AI is harming them right now.

Like many professors, I sometimes get bizarre requests from members of the public with an, ahem, scientific interest. This one ranks high on the bizarro scale!
Screenshot of an email message, with the text: "Hello Lorena

You have a great course in CFD. Unfortunately, CFD is not my expertise but I need hurricane modeling done for a project. Can you or a student in your group perform a feasibility study and report results?

The project is hurricane defense. I want to use explosive ordinance to disrupt hurricane formation to prevent hurricanes from making landfall. Hurricanes cause catastrophic damage and we severely lack defense for it."

Here's a thought—what if we just, you know, stopped using number of publications as a measure of researcher quality? What if we decided that "publish or perish" was a bad idea from the start? Just at thought. Anyway, fascinating thread here!
